Why are 90 percent of the reviews K-girls on TER.  There are hardly any Tryst or PD girls reviewed here.  I am missing something?

I think your percentage is wildly inflated.  Sure, if you go to an area like San Jose, Ca, then yes, it will be dominated by Kgirls.  Probably because they do the most business there.  Look in the State of Florida where I live, and there is one small Kgirl agency in Miami.  They've had only a handful of reviews in the last year.

Yes!

Or have their profiles behind a login so they cannot get reviews.  The K Orgs are easy to book and often have alte available when the one I want is not free.  Some of the Indy providers on here I have either gotten fed up with screening or schedule didn't line up.

Lots of kgirls having los of sessions with lots of reviewers for half what a typical independent charges.
Kgirls don't  (typically) complain about reviews.  
Kgirls come and go and change names in different cities.
TER doesn't allow reviews from PD girls as it is also considered a review site.
More and more younger independents don't value or encourage TER reviews to build their reputation.  

Yeah, I don't know why this claim keeps coming up as it's been shown to be false time and time again.

Trying not to make this sound rude, but you could contribute more too. You have 3 reviews, from 2001 and 2014 (presumably the third delisted). So you have been on this site for 23 years and only contributed 3 reviews total.

Yes,they are in many places and are  well reviewed but not the majority and don't amount  to 90 % in my opinion.  
I think the  reviews numbers  are a result of an obsession with Asian women , the erotic massages, their petiteness (some people are obsessed with that ),the extras (bareback), their submissive nature, and yes the price.

put this on the Kgirl board!
You probably would have received better answers, you never know!

where there are thousands of potential customers, Kgirls have been slowly increasing market share over the past 25 years.  They get more customers, so that's why there are more reviews.  I would be willing to bet that if someone did a scholarly study on this, they would find the Kgirls get reviews in a similar proportion as indies.  There was one legendary Kgirl in LA that is the only one I know of that got over 200 reviews in one year, but I know for a fact she saw between 1800 and 2000 customers that year.  

But it all depends on what market you're in. In my market, it sure seems that way to me. They/Kgirls have flooded the reviews in some places. And my feeling is that some reviews are agency/booker planted and that TER gives the agencies alot of leeway.
When you think about it, TER needs the Kgirls, and the Kgirls need TER..its a good match

Maybe he is got a 'no kiss and tell' policy.  Unda cova  lova . May 'Little John' fell asleep and can't wake up.
